AI Technical Summary

⚠Technical Problem

Existing electronic components with negative temperature coefficients face challenges in controlling self-heating, leading to potential thermal runaway and integration issues, particularly in power electronics, where miniaturization is difficult due to the need for large heat sinks.

⚗Method used

Incorporating a thermistor with a positive temperature coefficient in series with the electronic component, thermally coupled to limit current and maintain the component's temperature within a setpoint range, using a thermal resistance less than 1K/W to stabilize the component near the setpoint temperature.

🎯Benefits of technology

The solution effectively limits self-heating and maintains component temperature, preventing thermal runaway and ensuring even current distribution among paralleled components, thereby extending component lifespan and reducing integration challenges.
